A process for producing a glass-coated article having a silicon substrate and the article produced thereby are provided. According to the process of the present invention, a layer of glass wetting agent material is formed on the substrate to improve wetting of a glass material to the article. A desired thickness of the glass material is applied to the layer of wetting agent material. The article is then fired and subjected to ambient conditions sufficient to melt the glass material and to form a substantially uniform layer of glass material that is substantially devoid of void pockets and deformities. Particular utility for the present invention is found in the areas of fabrication of electronic circuit boards and semiconductor devices, although other utilities are contemplated.
